II IIIIIII INVENTOR feessie.

To all @ehem/t may concern.' i e Y .Be it known that I, vEnwrn E.` SLIoK, a citizen of the United States, yand a resident of the borough of Westmont," county ofV Cambria, and State of Pennsylvania, (whose ypost-oflice address is Johnstowm Pennsylran1a,) haveinvented Certain new and 'usa ful. Improvements in rIruck Side Frames;`

and I do 1hereby declare th'e'following to be a full, clear, and exact descriptionof `the invention, such as will enablelothers lskilled in the art to which it appertains to make and use the same. e l l e My invention relates to improvements in car trucks and particularlyvthose which jare adapted to support heavyfreightor other cars and refers generally to that part of the oar truck composing thetruck side frame which Iunake of wrought orrolled iron or Steel, parts of which may be pressed into` final shape and secured together in variousvways.

Bymakingmy truck side frame of rolled steel ofproper and knownlqualities, Lprovide 4a material which by reason -of its method of manufacture, inspection and tests, is sure to be solid and integral throughout each part thereof in" such `a way that each member is best adapted to withstandthe stresses and strainsto which it may be subjected in use.` Imay secure the various portions together-byplbolts, welding, hot driven or cold driven rivets, but prefer to use rivets which are solidly driven byheavy pressure into holes drilled through the solid metal of the contiguouspartsor punched with holes considerably smaller thanV their finished size `and then drilled or'reamed so that each "hole e is smooth and ofuniform size throughout.

. I preferably constructjthe lower member of-my truck side frame from` a plate of rolled steel` which i is approximately rectangular and withparallel sides, except that" the ends 'maybe cut ofi `on a slight taper or Abevel if desired,` to redueethe weight and size of the end portions. This memberfmay be rolled or pressed into general `U-seetion withthe web portion below and the flanges extending upwardly therefrom, the intermediate. portion fof the flanges also being flanged outwardly to form a broader portion for the e spring seat( which` supports the springs on which the endsl of the holsters rest. .s This lower member `is formed substantially" in the shape a V with, however,` a

straight lower `portion connecting (the two riveted thereto through and by means of the `of reference on the drawings :e-l represents "I Ifrlfll Ifllfl. rfDw'nvnsLIoK, or wiss'rmoivrebdibnen, reimsrminIn.e` l l ...li'l a 'rauen srnnrnnrvrn.

eithermade of rolled orpressedsteel, asdevsired, and" of such width` that it may be nestedfwithin the ends of or betweenthe flanges of the lower member andjsecurely contiguousflanges.` I also provide another brace member for the truck side frame, the general form of which is ll-shape and in aol` dition to this `the cross section ofthe same is generally of IIJ-shape `with flat lower or webportions, and this member is adapted to be nested within the lower portion of the bottom arch bar member andthe upper poi`` tions of Athisbraee member areadapted to be secured to the flangesof the uppeiyarch bar member. I thus provideatruss-construction `which ,is amply `braced inl all directions and able to withstandthe stresses'to which it is subjected while thus providing` a framewhicfh is as light as or lighter thana frameof any other construction adapted to carry the same loadl In additionto the foregoing portions, I also provide the usual spring seatU pedestal tiefbars, column guides,` brake-hanger supports and e journal-box` bolts.

Having thus given a general description ofmy invention, I `will nowrefer to the `annexed. sheet of drawings in which like Lchar* acters refer to likeparts ligure` lis a side elevation of `a `railwaytruck provided with a side frame embodying myinventiong Fig.

2 is a topplan view `of the si'defral'me; Fig. Y 3 isja transverse sectional elevation taken on the line III- III of Fig.- il; Figzpl is a plan viewof aplate from which the loweror inverted arch bar l is` formed; Fig. `5 is a; top plan view the `lower or inverted arch` bar after it "has been `formed in the" desired shape; 4Fi 6'? transverse section thror rh the truck column andguidetaken on the e VIT-VI of Fig. 3 g and Fi g. 7 is a transve seeti on through the truck column and guide, showing a 'modified form of column guide.

e Referring now to the various characters the top member or upper archxbar which shown as of channel section, which" channel may be either first rolled and then `cambered or bent to a slightdegree as shown,l orit may be Aforrrled* 'from a e fiat plate which 1 pressed into the shape shown. 2 represents the bottom member or lower arch bar in general and thisisof channel section with aA web portion, as illustrated, and with two fianges projecting substantially parallel and in the same direction therefrom. This lower 'member may first be rolled of channelsection with a web and' twovianges, as illustrated, and then bent into the shape shown in Fig. '1 and the flanges then formed there- `on to provide supportsfor the spring seat, or it may be pressed' from a flat plate of rolled steel indicated as 2st inA Fig. 4. This lower vmember is provided'with portions 3 which incline upwardly from each end of the lower portion thereof and with substantially thori- Zvontal end portions "f the lower parts of which are'adapted to rest on top ofthe journal bo'Xes as illustrated. The ,upper arch bar y1 is provided'with side'flan'ges 5' which l are nested within and secured to the ends of l ythe lower member by rivets, as illustrated,

and: also secured to the truck column memp ber Slby rivets' passing through the fianges 5 andthe portions 9 of thetruckcolumn, as

illustrated. `Flanges ,6- are formed "integrally on the lower portion of the inverted varchbar 2, adapted-to receive the spring seat plate 18 secured thereto byrivets, asillustrated. The journal looxes'are illustrated at i' The truck columns 8 are formed of channelfsection which `may be either rolled vor pressed from applate and thenbent into U- shape as illustrated, the sides extending .vertically and the bottom `member being nested within and secured tothe contiguous portions of the lower'aroh bar ymember by meansfoffrivets, as illustrated. This truck column 8by reason of its construction and the Yfact that .itis firmly secured to the'finverted arch bar and@ also firmly riveted through itsv flanges 9 by Va number Vof rivets yto the vupper4 arch bar,.forms a very efficient4 brace which adds materially to the strength of the structure, while', at. the same time,

serving tosupportthe column guides 10 andA ll'andf The column guide'. 10 is preferably formed ofafbent plateinserted between the flangesof Ythetruck columny 8 and riveted thereto, as shown, thezinneryends of which project towardthe bolster-and form a guide ptherefn'. AOn these cohnnnfv guides I.V may apply a weanplatell riveted thereto "by countersunk rivets, in order to provide a smooth surface, as illustrated in Fig. C, or .lV

Vmay make the columnguide in one piece, as

illustrated in Fig. 7, 1n which the lateral guiding edges of the column guide are 2G,

the flanO'es or les are 27 the modified form of column guide itself in general being indicated at 25. In the ends of the upper arch bar'I provide bolt holes 12 and 13 and in the ends ofthe lower arch bar I provide bolt holes- 1li and 1 5, which are adapted to receive bolts 1G and 17 which secure the journal boxes to the truck side frame and which also secure the pedestal tie-bars Q3 thereto. 19 is a spring` plank which is of channel section, one end being riveted to one side frame and the other to the companion side frame on the other side of the truck, this spring plank thereby holding the two side frames squarely together to make. them act harmoniously in service. The springs which are shown as of helical form are illustrated at 20, the bolster is '21, the brake hanger carrier is 22, while the pedestal tic-bars are Inorder to obtain the maximum amount of stiffness and strength at the end of my side frame, I prefer to nest the upper member within the lower member with their webs spaced apart, as illustrated particularly in Fig. l.

Although I have shown the upper arch bar member 1 with its fianges 5 projecting upwardly, as in this position it is more easily secured to the fianges of the lower arch har member, as illustrated, I may also arrange the upper member 1 with its flanges 5 project-ing downwardly andl with its web portion forming the upper part of the truck frame, as on account of the considerable space within the ends of' my truck frame I can introduce rivet-ing tools therein and secure the. parts when they are placed together in this latter manner. In this case I ma)v also make the upper arch bar member of width sufficient so that'its flanges may overlap and be outside `of Vthe, flanges of tln` lower arch bar member. One of the partielllar features of my invention constts in forming the-various members of trough or channel section and nesting portions of the same within portions of theothcr members and securing. them together by their contiguous sides. as illustrated.

Although I have shown the upper arch bar member 1 as of channel or trough section with vits flanges projecting upwardlv. I may make it of other sections. such as rectangular, square bar, I-hcani. box-shape or other `shape as may be readily understood.

Although I have described and illustrated myv'invention in ctn'isidcrable detail, I do not kwish tobe limited to the exact-,and specificl details thereof, as shown and described, but may usc such modifications in. substitutions for, or equivalents thereof, as are emlla tr `i-ughsection, the" ends "ofone member beingniested within the *ends of' `the other with their Vwebs 1'spaced' apart and" their' flanges contiguous and securedtogether.
